Hi, just as a heads up if you are not familiar with Decker, its audio capabilities out of the box are pretty limited. Essentially, it is limited to sound clips of a maxmimum of 10 seconds, in 8khz 8-bit mono. So it's pretty low-fi.
You can string clips together with a bit of programming, or use something like my own JankyTunes library (which is essentially a very primitive chiptune player) but generally it's pretty limited.
Just thought you should know what the limitations are before you joined a project and smashed out like a 2 minute song that may be a bit tricky to use in Decker, haha.
